摘要
A dual rotor, manually steered riding trowel comprises powered, downwardly projecting rotors driven by reduction gear boxes that are tilted by parallel levers beneath the machine. A pair of vertical hand steering levers actuate the parallel levers to tilt the rotors. Each rotor may be swiveled in an arc parallel with the biaxial plane to produce pivoted fore and aft trowel movement. At least one rotor responds to lateral movements of one or both steering levers by tilting in an arc perpendicular to the biaxial plane, moving the trowel left or right. To emulate prior Allen trowels, lateral movements of one of the hand levers is mechanically disabled with a transformation link anchored to the frame. The transformation link may be disconnected from the frame and instead connected to the foot of the companion hand steering lever, allowing both steering levers to pivot laterally, resulting in a different steering “feel.”
